Creating Hardlinks and Symlinks in Android

I am creating an app in which I would like to make use of hardlinks and symlinks in the Android external memory filesystem. I have tried using the commands

Os.link("oldpath", "newpath");
Os.link("oldpath", "newpath");

However, when I try this, I get this error:

link failed: EPERM (Operation not permitted)

This makes me think that you need root access, although I have seen other people do this same thing, and I would not think that they would have these commands if they needed root. Any ideas?

android Oreo(API 26) add Files.createLink and FileSystemProvider.createLink for hard link.

android lollipop(API 21) add Os.link for hard link

API 26 also add LinkPermission("hard") and LinkPermission("symbolic"), but I do not know how to use them.
